Abstract

BACKGROUND: Although free tissue-transfer with the deep inferior epigastric perforator (DIEP) flap is one of the best forms of autologous breast reconstruction, surgeons have remained guarded over selecting patients for the procedure in the presence of comorbid conditions. This study has investigated the relevance of these conditions. METHODS: A prospective review of all free flap breast reconstructions (n = 624) was performed over a 2-year period at the Department of Plastic Surgery at the Sana Kliniken Düsseldorf. Patients were placed into three groups based on comorbid conditions such as age 65 years or older, active smoking, and body mass index greater than or equal to 30. Flap and donor-site complications were analyzed. RESULTS: Six hundred twenty-four breast reconstructions with DIEP or muscle-sparing transverse rectus abdominis musculocutaneous (TRAM) flaps were performed in 558 patients (66 bilateral reconstructions). There were 36 patients older than 65 years at the time of surgery, 94 active smokers, and 79 patients with a body mass index of greater than or equal to 30. Flap complications such as venous congestion (n = 5), partial flap loss (n = 10), marginal necrosis (n = 15), and total flap loss (n = 5) occurred in 35 cases (5.6 percent). Donor-site complications such as delayed abdominal wound healing (n = 9), seroma (n = 8), abdominal hernia (n = 3), and bulging (n = 11) occurred in 31 cases (5 percent). CONCLUSIONS: Despite having significantly higher complications in the form of delayed donor-site wound healing in active smokers and higher total flap loss in obese patients, the overall complication rates compared with other reconstructive procedures are low. Microsurgical reconstruction with DIEP and muscle-sparing TRAM flaps is associated with low complication rates, excellent aesthetic outcome, and high patient satisfaction, even in patients with known risk factors.

Why This Matters for Hirudotherapy

This prospective single-center series (Seidenstuecker et al., 2011) reviewed 624 free-flap breast reconstructions (DIEP and muscle-sparing TRAM) in 558 patients, stratified by comorbidities (age 65 or older, active smoking, BMI 30 or above), and found overall flap complications in 35 cases (5.6%) including venous congestion in 5, with higher delayed donor-site healing in smokers and higher total flap loss in obese patients but low overall complication rates even in higher-risk patients. For ASH it provides denominator context on how often venous congestion and flap loss occur in modern microsurgical reconstruction, the setting in which leeches are used for congested flap salvage. Caveat: this is an observational cohort describing surgical outcomes and risk factors; it does not study or mention leech therapy, and the small number of venous-congestion events limits inferences about salvage approaches.
